Application filed November 5, 1889. Serial No.829,322. (No model.)Patented in England December 21, 1888, No. 18,668; in France October 9,1889, No. 201,217, and in Switzerland October 28, 1889,1Tc. 1,559.

To thisupper part Q2 we prolong the base of each of said pedestals 5o issecured the front iiy-plate QS-ftl e., a steel and cast the aforesaidhollow box in such pro- Ioc longed portion, as shown applied to thelickerin pedestal, Fig. 4.

We recess the ends of the cylinder u, as shown in Fig. 7, by placing therings and end plates thereof a certain distance back from the edge ofthe cylinder in the usual known manner, leaving the body of the bendtoutside the cylinder, and continue the bearing or socket 0c of thecylinder-pedestal a: for a short distance, so that the said bearing orsocket .r projects equally, or nearly so, on each side of the body ofthe under-framing s, whereby the pressure of the weight of the cylinderu is brought over apoint at the inidwidth of the framing. We mayfurthermake provision for strengthening the said framing s to sustain theweight of the cylinder u by carrying down webs or feathers s from theupper fiange of the main framing s to a strong foot or feet s2, formedon the said 'framing to rest upon the Iioor.

Ve apply our improvements also to the rsetting and construction of theunder-casing of the main cylinder u and licker-in w, and also to whatare termed the back knives y2, which cover that portion of the cylinderu between the licker-in and flats, and the other back knives y, whichare attached to the licker-in pedestals y. Thus we may have a pedestalor sliding frame y, supporting a segmental piece y', upon which arescrewed the said back knives y2. By screws @f1 the back end of theunder-casing 1,13 or the segmental piece y may be secured so as toextend below the underframing s and the back end of the under-casing yshinged or otherwise attached thereto, as shown in Fig. 6. frame y, withthe under-casing g5 of the licker-in, the casings y if, and the backknives y2 @/6, are adjusted by means of the improved setting apparatushereinbefore described, and lshown applied to the licker-in pedestals yin Fig. 4. As far as the combined adjustment which affects both thelicker-in and the under-casing is concerned, there is no differencebetween having the back end of the casing secured by screws to piece yand having said back end hinged to said piece but it is obvious thatthere will be a difference when the setting of the front end of theunder-casing is effected by means of the swinging bracket .e or itsequivalent. As in the case of the screws, the back of the end of theunder-casing is rigidly attached to the piece y', and in the second caseit is hinged to the said piece. le might cm ploy any ordinary adjustingappliances; but We prefer to employ our improved adjusting device, asshown and described, as our object is to simplify the operation ofadjusting and enable the parts of this portion of the carding-engine tobe set with the greatest accuracy. It will thus be seen that applicantshave one adjustment which affects both the licker-in and undercasings.

We prefer to adj ust the central part or front end of the under-casing@/3 and test the ad- This scribed, to keep them as nearly as possiblethe same relative distance from the working parts, it becomes desirableto adjust, also, the central part or front end of' the under-casing p3.The front end of the said under-casing p3 is according to ourimprovements carried on each side of the carding-engine by a stronghanging brackets' from the boss 0r socket zr', which carries the bearingfor the cylinder-shaftu, around which the said hanging bracket e maymove when the under-cas ing fyg is adjusted with the other parts by thesetting apparatus. The front end or central portion of the under-casingg3 may approach within a shortl distance of the metal blade q, which isattached to the front under-casing. q', near the under-casing t/, andmoves with thesliding frame q, and we may have a hole or opening 33 insome portion'of the underframing s, that will permit a gage to be passedbetween the under-casing and the wireof the cylinder u, so that if thespace becomes too great, which is easily observable, the hanging bracket.e on each side of the engine,which is provided with an adjusting-screwz', can be made therewith to raise or adjust the front end of theunder-casing ys to the required position; or we may employ either of thedevices shown in Figs. 8 to 12 in order to support and guide the frontend and central portion of the under-casing ys when the latter isadjusted.

rlhe devices shown in Figs. S, 9, and lO consist of stationary brackets22,v bolted to the under-framing s and carrying studs 54, preferablyprovided with anti-friction bowls, upon which the prepared inclined orslotted surface of the under-casing ys moves when adj usted. In Fig. 8the inclined surface is made by notching the under-casing y, In Fig. 9it is made by forming a projection on p3, and in Fig. l0 it is made byforming a diagonal slot in @/3, the action in each case being the same,as when the under-casing ya is moved endwise the inclined surface,moving on the studs carried by the brackets z, causes the under-casingya to be adj usted relative to the cylinder.

In Fig. ll the stud e4 is on the under-casing` g3 and the preparedsurface on the bracket 52.

In Fig. l2 the under-casing @/3 is shown simply connected to theunder-framing by a pivoted link es, which would support the undercasingys and guide it during adjustment.

For the purpose of testing the adjustment of the various covers andcasings we form bosses s4 upon the framing opposite the cir- IIOcumference of the wire of the working parts. Each of these bosses s4 isbored out and fitted with a cover, which may be screwed in or fastenedby a set-screw or hinged to the framing, as shown. Then the settingrequires to be adjusted, the covers are removed or swung back on theirhinges and a thin gage passed through one of the holes and between thewire and the working parts, and when the adjustment has been effectedthe stop-pieces or covers are replaced. iife do not limit ourselves tothe position or number of these.

Having now particularly described and ascertained the nature of our saidinvention and in what manner the same is to be performed, we declarethat what we claim, and desire to secure by Letters Patent of the UnitedStates, 1s-

l. The combination, with the bend-nose or side framing q of the doffer,uuder-framing s, and segmental piece q', forming part of side framing qand extending upward on each side of the engine, of means forsimultaneously adjusting the abovementioned parts, substantially as setforth.

2. The combination, with the bend-nose q, under-framing s, and segmentalpiece q', forming part of the bend-nose and extending above -and belowthe under-framing on each side of the engine and carrying the undercasing or casings between the main cylinder and doffer, of means forsimultaneously adjusting the above-mentioned parts, substantially asherein set forth.

3. The combination consisting of the -mov able frame q, segmental pieceor pieces q', door or lap pieces q2, front fly-plate g3, the metalunder-casing or blades g4, the hollow box g5, and setting devices, oneon each side of the engine, substantially as set forth..

Il. The combination, with the licher-in pedestals y, under-framing s,and a segmental piece y above the under-framing on each side of theengine, said segmental piece carrying the back knives y2, of means foradjusting the whole simultaneously, substantially as specified.

5. The combinatiomwith the licher-in ped estals y and undencasing g5,under-framing s, cylinderunder-casing ya, anda segmentalpiece y on eachside of the engine, said piece above the under-framing carrying the backknives y2 and below supporting the cylinder undercasing yi, of means foradjusting the abovementioned parts simultaneously, substantially asspecified.

6. The combination, with the main cylinder and an under-casing therefor,of the hanging bracket e, provided with an adj listing-screw e", wherebythe front end of the undencasing can be raised and adjusted to thedesired po sition, substantially as set forth.

7. The combination,with an under-casingy3 for the main cylinder,adjustable with the pedestals of the lickerdn, of means for sup port-ingand guiding the front end of the under-easing ys when the latter isadjusted, sub stantially as set forth.

In testimony that we claim the foregoing as our invention we have signedour names, in presence of two witnesses, this 21st day of October, 1889.
